The idea that managers can attend to a few things well but many things poorly. Simplification refers both to the use of fewer, not more, metrics, objectives and goals, and the idea that multiple measures should be distilled down into single measures like an index or a simple catch-all question. For instance, GE’s use of the single question about referring customers is a powerful but effective leading metric and a metric that it can reinforce with its rewards system. When metrics involve multiple dimensions, in areas where the organization wants to gauge customer satisfaction, for example, a survey can have 10 or more questions. Think about the many customer satisfaction surveys you are asked to complete after making an online purchase. Which question is the most important? The challenge, of course, is that a simple average of the customer survey scores, while providing a simpler indicator, also may hide some key indicator that is now buried in the average score. Therefore, the organization might need to experiment a bit with different ways of simplifying the measures with the aim of providing one that best reflects achievement of the key objective.
